VALVE.

Application filed January 29, 1927. Serial No. 164,609.

rIhis invention relates to valves and more particularly to valvesintended tor use in connection with h ot lair heaters for use in heatingthe interiors of vehicles. `1'The objects of this invention are toprovide valve of improved construction which may be set to one positionfor admitting warmed air to the interior of a vehicle and intorano'therposition to provide for the discharge of the warmed air to theatmosphere when. not required in the interior'of the vehicle g' also toprovide a valve of this hind with nieans for securely holding thevarious parts in theircorrect relation despite the vibration to. whichYthe valve is subjected when the vehicle is in use; also to improve thecoiistruction of valves of this kind so that the Operation of the valvewill not be interfered with by dirt or other foreign matter; also toimprove'thc construction ot valves ot this kind in other respectshereinafter specified. I' In the accompanying drawings:

I) represents thefloor of the vehicle.

The valvev tor controlling the flow of hot air trom the branch pipe orduct b to the or duct C preferably includes a housing made of? a dishedor recessed housing menibeii8 and acover plate 9 thereforiwhich may besuitably secured to the open end of the recessed housing 8.. Thehousinga and cover'plateY 9 are Vi'greferably made ot sheet metalstamped and formed into the desired shapxesy'although they may be madeof other material, if desired. 'Ihe housing and cover plate are providedwith openings 10 and 11, preferably arranged opposite to each other, theopening 10 in the housing 8 being provided with an outwardly extendingflange 12, and the opening 11 in the cover portion 9 being provided withan outwardly extending flange 13. A short tube or sleeve portion 14,- ispreferably secured to the flange l2 and is adapted to be connected withthe branch pipe b of the jacket B in any suitable ma'nnver. In theparticular construction shown, this branch pipe b extends into the shorttube or sleeve 14, and a bolt 15 extending through holes in the sleeveand pipe serves to secure these two parts rigidly together. In a similarmanner, a short sleeve or tube 1'? is secured to the flange 1B oft thecover 9 and the pipe C tele# scopes over the short tube 17 andisheld inplace by means of a bolt 1810i' the like. Any other means for connectingthe valve hous ing with the hot air inlet and discharge pipes may beemployed.

Then it is desired to heat the vehicle the valve is moved to a positionin which the duct C is open and unobstructed and wai-in from the branchpipe b will pass through the o ppositely arranged holes or openings l0and ll in the parts '8 and 9ct the housing, and thence into the pipe C,from where it may be distributed to any desired part of the vehicle. Itthe interior oi the vehicle becomes heated so that it is desired tointerrupt this flow of heated air into the body of the vehicle, this canbe done by moving a valve plate 20, arranged iii the valve housing andpreferably slidable in contact with the substantially lat cover portion9 there of, downwardly to close the hole 11 in the cover' portion andcut ott or obstruct the entrance ot heated, air to the duct C. In orderto prevent the accumulation of hot air in the space between the jacket Band the ei; haust pipe, when the valve 20, is in the latter position,roni causing overheating Aof the exhaust pipe, means are provided tordischarging or 'venting the heated air out oi the housing of the valveyVwhen the opening 11 is closed, and `for this purpose, in theparticularnconstruction shown, the plate 2t);l is provided with a'holeor opening 21 which is adapted to register with a corresponding opening22 in the cover plate 9 ofthe valve when the valve is in itsduct closingposition, as shown in Fig. l, in which case the Ilv warm air enteringfrom the branch pipe b through the hole in the portion 8 of the. housingpasses upwardly through the lower, hollow portion ot' the housing andout ot th same through the holes 21 and respectively in the valve andthe cover plate 9, the hole 22 in the cover plate being open to theatiuosi'ihere underneath the floor D of the body ot the vehicle. Thevalve plate or member 2O may be guided in its duct opening and ductclosing and venting positions in any desired manner, for example theplate may be provided at opposite sides thereof with flanges whichextend along the opposite sides ot' the depression in the housing member8, as is clearly shown in Fig. 5, and guide the valve pla-te in itsmovement. In order to prevent dirt and other foreign matter fromentering into the housing of the valve and interfering with theoperation thereof, a suitable cap or guard 24 is preferably placed overthe opening 22 in the cover plate 9, this guard in the constructionshown being substantially semi-circular in t'orm and being open at itslower end, as indicated at to permit heat-ed air to be dischargedtherefrom. By arranging this guard 24 directly over a pipe, such as thepipe C, or the short pipe 17, the sl'ilashing otl mud, water or otherforeign matter upwardly into the guard is to a large extent prevented.

The valve plate 2O has a stem or extension 27 which extends out of thehousing member S through a suitable opening therein through which thestem portion 27 of the valve may be moved into either operative positionin any suitable or desired manner. Means are preferably provided torholding the valve yieldinglv in either position and also for pressingthe valve against a part ot the housing to prevent rattling. In theparticular construction shown, a spring isuscd tor this purpose, whichis made ot a single piece of wire provided with two coils 29, the ends30 0f the wire bein,f l secured to the valve plate 2O in any suitablemanner, for example, by means ot rivets 31 extending thro-ugh loopsformed in the ends ot the wire and through the valve plate. The innerend:-` of the two coils 29 terminate in arms 32 connected by atransverse part 32a of the spring, around which an anti-friction rolleror sleeve- 33 is arranged, which may, it' desired, be. in the form of a.coil of wire. The spring, act` ing through the roller 33, holds thevalve plate 2O in either its duet opening or duct closing and ventingposition. For this purpose the portion 8 of the housing is provided witha pair of recesses 34 and 35 in which the roller 33 or other part of thespring may enter to yieldingly hold the valve plate in either position,the depression 35 being arranged so that when the spring roller hasentered into this depression, the valve will be yieldingly held in itsduct opening position. and the depression 34 being arranged so as tohold the. valve in its duct closing \.'enting position. This spring inadnition to holding the valve yieldingly in either operative position,also presses the gjainst the cover plate 9 ot the housi..g as to Vlorm atight closure with either ci the holes 11 or 22 therein, and furthermorethe spring prevents rattling of the valve member.

'V ion ot the valve by raising or s ein or part 27 secured thereto nr=ybe ellected in any suitable or desired anner. ln the particularconstruction shown this is done by means of a rod 37 extending throughthe floor D of the body ot the vehicle, this rod 37 being connected Withthe stem 27 of the valve in any suitable manner to permit a certainamount of adjustment of the rod 37 relatively to the valve Q stem 27.The rod 37 is preferably provided at its upper Vend with a knob orhandle 38 by means of which the rod may be raised and lm-vered and thelower end of the rod connected in any suitable manner, for example, bymeans of nuts 39 engaging the lower threaded end of the valve adjustingrod to one end ot a cross piece 40, the other end ot which is secured toa laterally extending or bent arm ll1 of the valve stem 27, by means ofa bolt 42 Wnic-h extends through slot 43 in the arm 41. By means of thisconnection a considerable amount ot adjustment can be eli'iected betweenthe valve adjusting rod 37 and the valve stem 27 since the connectinglink or plate may be swung about the axis of the bolt fit-2 and also maybe adjusted relatively' to the lateral extension 41 to thc extent of thelength of the slot 43. Consequently it is not necessary to aline the.hole in the floor of the body ot the vehicle through which the rod 37 prjects with the handle portion `27 or the valve which is arranged beneaththe floor. Other means for actuating the valve may, t course, beemployed, it desired.

The valve described is simple and durable in construction and can bemade entirely of sheet metal and affords an ellicient closure for thewarm air passage and also a vent or discharge for the warm air in casethe passage to the interior ot' the vehicle is closed. The valve is seltcleansing in that the lower edge of the movable valve. member willscrape any deposit ot dirt or foreign matter from the edges of the hole11 and thus insure at all times a tight closure When the valve is in itsduct closing and venting position.
